Abstract

The objective of this research is to determine the appropriate numbers of Container Yard (CY) for rubber and wood rubber transportation using railway in Southern of Thailand. The location allocation problem concept (LAP) and ArcGIS 10.2 program are employed for this research. There are three circumstances to analyze this problem: 1) modal shift from road to rail using two existing CYs, 2) modal shift from road to rail using two existing CYs and four new CYs according to Thai Railway plan, and 3) modal shift from road to rail using two existing CYs and five new CYs resulting from group discussions. The result indicates that the third situation with 6 CYs provides the lowest transportation cost. The transportation cost decreases from 1,097,496,213 Baht/year to 898,307,550 Baht/year, or 32% reduction. In term of investment analysis, the NPV is 4,000,109,320 baht, IRR is 171%, and the payback period is 1 year. All in all, an appropriate modal shift in freight transport shows a potential in transportation cost reduction. With this in mind, the research develops a vision of an efficient rail freight system in Southern of Thailand.
